Pollsters YouGov, which predicted the result of the 2008 election, said today: "Following a month in which he has faced criticism, there have been significant drops in the public's perceptions of Ken Livingstone."London government expert Tony Travers said revelations of Mr Livingstone's personal tax affairs had damaged his position, adding: "This is fascinating. The same happened in 2008 when Johnson started to pull ahead of Livingstone as election day approached."Perceptions of Ken appear to have been damaged by stories about his tax affairs.
